Is there any logical pattern?

Doh .... another grey Alps CM switch, this time linear-LED type. Surprising how many colours exist in linear with the LED recess. Might be a stiffer spring version, to avoid accidental keypresses, same as the MX Super Black.

In the SIIG MiniTouch, the top row switches differ in that the slider blocks (that stop the slider going down too far) are 1 mm taller, reducing the travel by 1 mm, from 4 mm to 3 mm. Plus the spring is longer and more tightly coiled.
